DEMOUNTABLE MULTI-PART CONTAINER ASSEMBLY BACKGROUND OF THE INVENTION This invention relates to containers which are assembled of two prefabricated parts preferably made of a synthetic material. They are of the type which have apertured walls and which accommodate carriers generally formed of absorbent pulp boards or plates impregnated with a volatile substance such as an insecticide, a perfume or the like.

It is known to arrange, in a container formed of a box-like lower part and an apertured lid, a volatile substance carrier in such a manner that a manual contacting of the carrier often impregnated with a poisonous substance) is made difficult.

After the volatile substance has evaporated, containers of the above-outlined type are usually replaced as a whole, since the danger of manually contacting the carriers in an attempt to effect an on-the-site exchange thereof is particularly great.

In containers of the above type, an intentional replacement of the carriers is made further difficult by the fact that the containers, because the gases emanating from the volatile substances are usually heavier than air, are often suspended at such heights that they can be reached from the floor only with the aid ofa ladder; thus a replacement of thevolatile substance carriers has to be effected by a person standing on a ladder or the like.

SUMMARY OF THE INVENTION It is an object of the invention to provide an improved container of the above-outlined type which is far more adapted for effecting replacements of the volatile substance carriers than containers known heretofore.

This object and others to become apparent as the specification progresses, are accomplished by the invention. according to which, briefly stated, the container comprises a first housing or base portion and a second housing portion releasably connected with the base portion. The base portion is alsoprovided with slide-in means for cooperating with the second housing portion. The second housing portion is provided with positioning devices that constitute the sole support for one or more carrier bodies. i

The structure according to the invention has the advantage that, for replacing the volatile substance carrier, the second housing portion may be separated from the base portion that remains attached to the wall and the replacement of the volatile substance carrier may be effected down on the floor with much less danger and inconvenience than it has been heretofore possible.

Further, the container designed according to the invention, makes possible, for the purpose of replacing the volatile substance carriers, a replacement of the entire second housing portion by an identical second housing portion containing unused carriers; whereby the replacement of the volatile substance carriers proper may be effected under laboratory conditions.

Also. the second housing portion is adapted to contain supports for a plurality of volatile substance carriers, so that one may arrange at will an arbitrary number of carriers in the container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning now to FIG. 1, the container for shielding the volatile substance carriers 1 essentially comprises a first housing portion or base portion 2 and a second housing portion 3 which is removably connectable with the base portion 2.

The base portion 2 has a closed rear wall 4 which includes a mounting orifice 5 with the aid of which the base portion 2 may be permanently attached (for example, by a scew) to a wall surface. The base portion 2 further has a floor 6 and a lid 7 extending in a parallel spaced relationship from opposite edges of the rear wall 4. The housing portion 3 may be removably slid into the base portion 2 between the components 6 and 7 in such a manner that the base portion 2 is entirely covered by the housing portion 3 and the container assembly thusscreens the volatile substance carriers 1 from all sides.

The frontal and lateral walls of the housing portion 3 are formed of spaced, edge-wise oriented horizontal slats 8 which are connected to one another by vertically extending guide rails 9 and border strips 10. In this manner large openings are provided in the housing portion 3 and yet a stable structure is obtained that affords sufficient protection against touching the volatile substance carrier from the outside.

Into each guide rail 9 there may be inserted a platelike volatile substance carrier 1 held in a frame 11 by which the carrier may be handled without the danger of manually contacting the volatile, sometimes poisonous substances. To ensure that the volatile substance carrier bodies 1 are also supported against displacement in the vertical direction, from the frame 11 of the carrier 1 there project laterally outwardly oriented fingers 12 which may extend into complemental cutouts 13 provided in each guide 9.

Further, the housing portion 3 is provided with parallel spaced guide grooves 14 designed in such a manner that the lid portion 7 and the floor 6, in the inserted position of the housing portion 3, will extend flush with respect to the frontal and lateral sides of the housing portion 3. This arrangement makes an unauthorized disassembly of the container particularly by children more difficult.

Preferably, the components 6 and 7 of the base portion 2 are so designed that they resiliently engage the sides of the housing portion 3 at the grooves 14. For this purpose it is also feasible to provide, for example, leaf springs in the grooves 14 which urge the components 6 and 7 outwardly and thus constitute a resilient bias therefor.

Turning now to the embodiment illustrated in FIGS. 2-4, the housing portion 3 is designed as an upwardly open box having a rear wall 3a, a front wall 3'b, a bottom 30 and side walls 3'11 and 3'e. The provision of the bottom 3'0 in the housing portion 3' is particularly advantageous in facilitating the cleaning of the container assembly. Further, for each volatile substance carrier body 1 (having, for example. a rectangular cross section) or 1' (having, for example, a circular cross section) there is provided one pair of grooved guide rails 9' into which a carrier body may be removably inserted. The two guide rails 9 of each pair are affixed to the rear wall 3'1! and the front wall 3'17, respectively, of the housing portion 3'.

It will be understood that the above description of the present invention is susceptible to various modifications, changes and adaptations and the same are intended to be comprehended within the meaning and range of equivalents of the appended claims.
